Answer:
By adding the solute in to solution boiling point is increased while freezing point is decreased.
Explanation:
When solute in added into the solvent the boiling point of solvent increases for example,
Water is boiled at 100 °C, when sodium chloride is added its boiling point increased. Ions of salt interact with solvent and prevent the water molecules to escape from the surface and form gas molecules. In order to make it boiled solution must be heated above 100 °C.
But there is different case with freezing point. Freezing point is the state in which substance converted into the solid. At given temperature when solute is added into the solvent it prevent the formation of solid. It required time to decrease the temperature first and as the temperature is decreases solid is formed.
I've put in some of the answers.
hope this helps :)
Least dense means the one that is at the top. Wood floats on top of water, so wood would be the least dense. Water has a density of 1 and the others would all sink, so they're more dense. The answer is wood
Azeotrope is a mixture of two or more liquids whose proportions cannot be changed by simple distillation.
Explanation:
Nitic acid and water is an example of azeotrope. The composition of 68% of nitric acid and 32% of water by mass in a boiling point of 393.5k.
The composition of perchloric acid (71.6%) and water boils at 203°c. Pure iron solution weights about 10g is placed in a beaker, hydrochloric acid and nitric acid mixtures are added and heated to dissolve. Add perchloric acid until it evaporate and produces white smoke.cool it down add water and dissolve the salt.
